Navisworks Clash Data Exporter & Power BI Reporting

The ultimate goal of these tools and workflow is to improve MEP BIM coordination communication with project teams. The Navisworks add-in provides a means to automate clash metrics progress reporting, visualize clash data, and make model data meaningful and accessible for various project stakeholders. This workflow requires Autodesk Navisworks Manage, Microsoft Power BI, and Navisworks API to access the desired Clash Detective data for exporting. The tools and workflow are designed to have Navisworks Manage coupled with Microsoft Power BI to deliver multiple interactive visual reports in Power BI. However, this respository focuses on the Navisworks API add-in. The included Power BI template is only for reference and testing.

Application Structure

Overall workflow from Navisworks Manage to Power BI

Navisworks Workflow Video

  1. The Clash Data Exporter add-in has two modules:
  • Clash Test - Exports specific Clash Detective data and writes in Excel spreadsheet
  • Total Objects by Discipline - Exports total objects in open model by discipline for producing metrics in Excel spreadsheet

  1. User prompted to specify focus zone associated with exported data and project disciplines

  1. Power BI Reports

Navisworks API Implementation

Below highlights specific API features implemented to access and export specific Clash Detective Data

Clash Test Module
  • How API is mapped to data in Clash Detective UI for OPEN clashes

  • How API is mapped to data in Clash Detective UI for CLOSED clashes

Total Objects By Discipline Module
  • How API is mapped to model files in Selection Tree UI

Output Excel Spreadsheet Examples
  • Export from Clash Test module

  • Export from Total Objects by Discipline module

Installing and Running Application

  1. Clone or download project.
  2. Open ClashData.sln in Visual Studio 2019.
  3. Ensure that the library packages stated in Getting Started are installed and referenced.
  4. The application can then be run in debug mode.
  5. Go to Debug/Release location and copy the files and folder below.

  6. Create a ClashData folder in Local_Drive:...\Autodesk\Navisworks Manage 2019\Plugins
  7. Paste copied files and folders to ClashData folder
  8. Open Navisworks Manage 2019 to execute and test add-in.
